STAMPING MACINE.

Application led August 20, 1923. Serial No. 658,419.

To all whom t may concern:

Be it known that we, EDUARD Gnrs'rniorr, JULns Rasr, Fnrrz KUMMER, and Fnrrz PAULI, all citizens of Switzerland, and residents of Lucerne, Switzerland, have invented a new and useful Improved Stamping Machine, of which the following is a specification, and for which we have filed applications in Switzerland on November 27, 1922, and in Germany on January 9, 1923.

This invention relates to a stamping machine apt to produce perfect imprints of artistic appearance and being suited to. form a complete substitute for postage stamps and the like. The machine is provided with an inking device which applies the ink so carefully that the iinenesses and niceties of the clichs, the use of which the invention renders possible, are distinctly reproduced. Among the stamps to be imprinted there is also one without a value-stating number, that stamp being intended for trial imprints; all stamps bearing value-stating numbers, as well as other stamps, are so arranged on an adjustable carrier and connected with counting devices for the imprints that on printing any stamp with value number not only a totalizing counting device is thrown into gear, but also a special or separate counting device pertaining to that special value stamp, whereas in the case of printing stamps without value numbers or the like all counting devices are thrown out of gear.

Our invention is illustrated by way of eX- ample in the accompanying drawings, in which Figure 1 is a side view of our improved machine. Figure 2 shows some details of the inking device in vertical section and drawn on an enlarged scale. Figure 3 is a plan of the parts shown in Figure 2. Figure 4L is a side view of some details of the drive. Figure 5 is a plan of some details of the means for throwing the counting devices into, and out of, gear, and for locking them. Figure 6 is a side view of the parts shown in Figure 5, in locking position. Figure 7 is also a plan of some details of the counting device gear. Figure 8 is a side view of some details relating to the means for operating the printing table. Figure 9 is a side view of some details relating to the means for actuating the inlring device. And Figure 10 is a side view of some details relating to the ink supply roller gear.

The printing stamps 7 which are formed by clichs bearing, generally, a value-stating number are arranged around a rotary adjustable carrier 6, the stamp 7L which bears no value number and serves merely for trial imprints being the last of the circular series. he adjustment of the rotary carrier in such a manner that a definite stamp lies just opposite to the printing table 8 is effected by an adjusting lever 2 which is turnable on a shaft 2EL and is in gear, by means of a cogged sector 5, with a cog-wheel secured to the shaft of the carrier 6. The lever 2 can be coupled with a sector 4; having recesses 4a and being afliXed to the frame of the machine, the coupling being effected by means of a pawl 3 attached to said lever. rlhe notches la are so spaced that each space is equivalent to any one of the spaces between the stamps 7 on the rotary carrier 6.

At the other end of the lever 2, near its pivot, is provided a short toothed sector or cogged bevel wheel part 9 meshing with a bevel wheel 10 and rotating it so much by the lever 2 that that counting device 13 is thrown into gear which pertains to the stamp located at the time being above the table 8. The respective counting device is thrown into gear by means of a cog-wheel 11 secured to the lower end of the shaft of the bevel-wheel 10 and meshing with circumferential cogs provided on a shiftable shaft 12 which is shifted in correspondence with the extent of movement of the lever 2 so that a lateral projection 14 provided at the shaft 12 arrives below a lever 15 of the counting device concerned, there being, as many such devices as there are value stamps in the machine, as may be judged from Figures 5 and 7. No counting device is, however, provided for the trial stamp 7a. as also already eX- plained.

Hinged to the lever 2 is a rod 16, the free end of which is formedas a rack whose teeth mesh with a pinion secured to a shaft 17 supported in movable arms 20 hinged to a shaft 57. The shaft 17 is provided with as many pins 18 as there are counting devices, and are distributed along and around their shaft 17 in a spiral arrangement, any one of the pins resting on the feeler head 19 of the appertaining counting device. There is this condition as regards the projections 14 and the levers 15 on one side and the pins 18 and the feeler heads 19 on the other side that the pin directed downwardly-at; the time being, and being, consequently, inoperative position, pertains to that feeler head and that.

Counting .mechanisme which can, be actuated by means of its lever 15 and the shiftableg.

projection 14.

Between each feelerhead 19 .the ape pertaining pin 18 is located a lever 56 which is also hinged to Athe shaftfl.: [Fhefree;l

end of each lever 56 is bent upwards in or der to prevent collision .between the feeler heads and thepins 18 when the. counting devicesv are thrownfi'nto igear.-v Bothxth'e pins 18. and their shaftl' .check the driving. de-

When 4the pawl 24 is .lifted yby means of the key 23, the disk 25 springsforward underthe action ofI the ,spring provided for this purpose, and the pawl vremains lifted upon the circumference 2 of the disk also after the key has been released; the circumference of the disk 25 at` the pointcconcerned is equal to the circumference of the disk 48. The hand crank 1a can now .be turned, the pawl 24 gliding then. .on the circumference of the .disk 48.

The lever 43 which carries the inking roller -44.\is subjected tothe pressure of the bottom surface-45 of theA ink receptacle f-.or container :3.7 whereby the ink carried :along bythe roller44is rubbedand finely vdistributed.Y Thefbottom. surface 45 isaplane in the example showns-infFigurel, but it may be slightly curved. The position of the bottom surface 45 relatively to the clich carrier 6 is such that it lies fiush with the lowest clich which is in position for printing. The inling roller 44 passes from the surface 45 to that clichJ and is guided between the said bottom surface and the respective cliche by rollers 44a, which are shown in Figure 3, and by ledges 58, of which one is shown in Figure 1, these rolls and ledges co-operating to guide the roller 44 to, and away from, the respective clich.

The ink supply roller 36 is so arranged in the ink-receptacle 37 that it forms a closure therefor. It is controlled by a cam 27, Fig. 10, and by levers and links 29, 30, 31, 32, 33, and 34, in such a manner that at each rotation of said cam a pawl 35 attached to the link or arm 34 acts on a ratchet wheel 35u secured to a shaft 36a and causes the inking roller to make a part rotation corresponding to one tooth or to several teeth, as the case may be, whereby a certain definite amount of ink is conveyed from the receptacle or container 37 to the inking roller 44.

The oscillations of the lever 42 by which the inking roller is turned are transmitted to the shaft 12 by a link 49 and a lever 50. The shaft 12 is that provided with the projections 14 which act on the lever 15 of the individual counting devices (Fig. 7). The lever 50 sits loosely on the shaft 12 but is coupled therewith by a longitudinal groove provided in this shaft, and by a projection extending from the lever 50 into said groove and forming a kind of feather, the arrangement being, thus, such that the shaft 12 can be shifted longitudinally in the eye part of the lever 50 but this latter remains stationary, the rocking motions being, however, transmitted by the feather and the groove mentioned. The shaft l2 makes only part rotations in one and the other direction, or rocking motions respectively, and that projection 14 which is located below a lever 15 of a counting device, whichever it may be at the time being, operates the respective counting device by 1, that is to say, to enhance the number by 1. Also the rod 59 by which the totalizer 60 is actuated may be connected with a suitable part of a controlled motion, for instance with the arm 55 carrying the printing table 8. The rod 59 may be suspended, for instance, by the intermediary of a pivot from a member 55b connecting the two arms of the double-lever 56 and pushes on the gear lever of the appertaining counting device when the arms 55 are swung upwards. If the clichJ 7LL which bears no value number is adjusted by the gear lever 2, the shaft 12 is shifted into its end position and throws out of gear, firstly, all individual counting devices 13 by means of the noses 1. A stamping' machine, comprising, in

combination, a plurality of clichs adapted to produce imprints representing various definite values; a table adapted to receive the object which is to receive the imprints, and means to press said table elastically against the clich located above it; an inking roller for the respective clich; and 'a corresponding number of individual counting devices for the various values and the imprints made .as regards them, substantially as set forth.

2. A stamping device, comprising, in combination, a definite plurality of stamps adapted to produce imprints bearing value signs; an ink-receptacle; an intermittently acting ink transferring member; an intermittently acting gear adapted to cause said member to take a definite amount of inlr out of said receptacle at each printing procedure; a plurality of counting devices for the various imprints made and corresponding to the various values the imprints show, substantially as set forth. 4

3. A stamping machine, comprising, in combination, a plurality of clichs adapted to produce imprints representing values; an inlr container for said clichs; a roller adapted to convey a certain amount of ink from said receptacle at each imprint; another roller adapted to transfer an equal amount of ink from said first-mentioned roller to the clich which is in printing position, and a member having a rubbing surface so located as to be adapted to co-operate with said second roller; and a corresponding plurality of counting devices for the various imprints and being so arranged as to be actuated singly, substantiallyas set forth.

4. A stamping machine, comprising, in combination, a plurality of clichs adapted to produce imprints bearing value signs; an ink receptacle, the bottom of which forms a rubbing surface; an inking roller adapted to move over said surface and to convey inl: from said receptacle to the clich which is in printing position; means to convey ink from the said receptacle to said roller; and a plurality of counting devices adapted to be actuated singly corresponding to the clich adjusted for printing and being actuated whilst the print is made, substantially as set forth.
